IMPROVEMENT IN COOKlNG-STOVES.

Specification forming part of Letters Patent No. 216,591, dated June 17,1879; application filed November 27, 1878.

To all whom it may concern Be it known that I, JOHN F. ALLEN, of NewYork, in the State of New York, have invented a new and usefulImprovement in (looking-Stoves, which improvement is fully set forth inthe following specification and accompanying drawings, in which- Figure1 is longitudinal section of a stove with my improvement attached, andFig. 2 is a top view of the same.

The object of my invention is to furnish a simple plan of producing thenecessary heat in a cooking-stove by the application of an oil, spirit,or petroleum lamp or gas burner, whenever it is not desired to make acoal fire in the stove--as, for example, when only little heat isrequired to cook withand when it is desirable to extinguish the firequickly, as in warm weather.

In the drawings, A represents a cooking stove, which may be of any knownconstruction and internal arrangement as regards the lines. B is thefire-door, H the fire-place, and G the ash-pi t and draft-door.

At or near the upper end of the fire-place H, where the flues begin, Iarrange a dia phragm, D, which may be made of sheet-iron loosely fittifig into this part of the fire-place, so as to shut the same ofi' from theother parts of the stove. This diaphragm D is provided with holes J, oneunder each hole in the top plate of the stove, and which may be closedby a suitable cover, if only one should be required. Into these holes Jcaps E are fitted,

having suitable projections n to rest upon the diaphragm D to supportthe same. The lower part of this cap is arranged to receive a suitablelamp, F, and is provided with a number of openings, S, to allow the airto pass into the same above the lamp F to feed the flame. At the top ofthe cap the usual longitudinal opening for the flame is made.

This arrangement of a petroleum lamp or burner can readily be fitted toany stove or range, whenever only little fire is required for a shorttime, as in the summer, and is quite as easily removed whenever a largeror coal fire is required. I

When the lamp is lighted the draft of air through the stove, which isadmitted and can easily be regulated by the doors B and G, must passnearly all through the openings S to the flame, increasing the densityof the same, and at the same time carrying all smell and smoke usuallyproduced by the burning of petroleum into the smoke-pipe.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

In combination with a cooking stove or range, the diaphragm D and lampor burner, F, fitted to a cap, E, provided with projections n andopenings B, said diaphragm D fitting into or upon the fire-place of thestove or range, substantially in the manner and for the purposedescribed.
